Windows Update Agent API and other OSes

Hello,

I'm having a little trouble with the Windows Update Agent API

(WUApiLib). I've got code working that pulls back a list of updates

from Microsoft, but they're specific to the system I'm running the

code on. I'm trying to figure out how to get the data for another

system. For example, I'd like to run the application on a Vista

system and get the updates for a Windows Server 2003 system. I've

looked at the ClientApplicationID property of the IUpdateSession

object, but it's always null.

I saw this post [http://groups.google.com/group/

microsoft.public.dotnet.general/browse_thread/thread/c8e7fc65ca13cdce/

dd31cc88e2543589?hl=en&lnk=st&q=WUApiLib

+ClientApplicationID#dd31cc88e2543589] asking the same question that I

am, but there was no response.

Does anyone have an idea of how to do this?

Here is working code (C#) that populates a listbox on a winform:

UpdateSessionClass updateSession = new UpdateSessionClass()

IUpdateSearcher updateSearcher =

updateSession.CreateUpdateSearcher()

ISearchResult searchResult = updateSearcher.Search(textBox1.Text)

for (int i = 0 i < searchResult.Updates.Count i++)

{

string KBs = string.Empty

IUpdate update = searchResult.Updates

UpdateCollection coll = update.BundledUpdates

for (int iu = 0 iu < coll.Count iu++)

{

IUpdateDownloadContent content = coll[iu].DownloadContents[0]

foreach (string s in update.KBArticleIDs)

{

KBs = s + ","

}

string title = string.Format("{0,-75}", update.Title)

string url = content.DownloadUrl != null ? content.DownloadUrl :

"No URL"

string displaystring = string.Format("KB: {0} Title: {1} Url:

{2}",KBs,title,url)

listBox1.Items.Add(displaystring)

}

}

Any thoughts or insight would be greatly appreciated,

Brian
